在托福阅读中，用关键词定位是很重要的一个步骤。定位能帮助我们节约时间，而且还可以提高答题的正确率。但是，在托福阅读中用关键词定位靠不靠谱呢?下面百利天下小编就为大家详细分析。
首先，跟小编一起看一个例题。TPO3-3 The Long-Term Stability of Ecosystems
5. According to paragraph 4, why is the question of ecosystem stability complicated?
A. The reasons for ecosystem change are not always clear.
B. Ecologists often confuse the word “stability” with the word “resilience.”
C. The exact meaning of the word “stability” is debated by ecologists.
D. There are many different answers to ecological questions.
从这道题目来看，根据关键词ecosystem stability complicated可以定位到这个段落的第一和第二句话：The question of ecosystem stability is complicated, however. The first problem is that ecologists do not all agree what “stability” means.第一句话总述段落内容，并没有给出ecosystem stability complicated的原因，而第二句话说出了ecosystem stability complicated的第一个问题是ecologists do not all agree what “stability” means，也就是说不是所有的生态学家都赞同“稳定”的含义，因此这个问题是复杂的，所以本题的答案是应该是C选项，环境稳定的问题得到生态学家的讨论
从这道题目可以看出，通过关键词定位对于答题来说，有很大的帮助，从这个方面来看，通过关键词定位是很靠谱的，但是小编要告诉大家的是不要过分依赖关键词所定位的句子。有时候需要考生结合关键词所在句子的前一句或者后一句进行答题，只根据一句话是无法找出答案的。
下面再看一道题，According to paragraph 4, which of the following is true of climax communities?
A. They are more resilient than pioneer communities.
B. They can be considered both the most and the least stable communities.
C. They are stable because they recover quickly after major disturbances.
D. They are the most resilient communities because they change the least over time.
根据这道题目中的关键词climax communities我们可以定位到文章中的两个地方，第一个是：In that case, the climax community would be considered the most stable, since, by definition, it changes the least over time.第二个地方是：In that case, climax communities would be the most fragile and the least stable, since they can require hundreds of years to return to the climax state.因此本道题目的答案必须要结合两个句子进行解答。第一点提到的是随着时间变化比较慢这一方面，climax communities是稳定的;第二点是从恢复来看，他们需要数百年，因此climax communities也是不稳定的，因此climax communities既是稳定的又是不稳定的，所以本题的答案为B选项。
从这到题目可以看出，通过关键词定位，是很有可能定位到不同的地方，但是考生要结合所有出现关键词的地方进行分析，并且总结答案，这样才能确保答案的正确率。
以上就是托福阅读关键词定位到底靠不靠谱的详细内容。大家在做题的过程中不能忽视定位的重要性，但是要根据实际情况选择并且综合定位的内容。最后，预祝大家在托福阅读考试中取得高分成绩!
